Be it known that'I, GEORGE E fPAGEfa citizen of the United States, andresiding at Rochester, Monroe county, StateofNewl York, have inventedcertain new and useful Improvements in' Sheet-Metal-Shaping Machines, ofwhich the following is a specification.

The present invention relates to shaping devices for sheet metalarticles. The object of the invention is to provide an apparatus bymeans of which tubular sheet metal members may be suitab-ly curved, forinstance, tubular spouts formed integral with sheet metal vessels orcontainers. In m copending application Serial No. 462,214, led April 18,1921, is disclosed a method of forming a tubular pouring spout for asheet metal vessel or container which is integral with the body of thevessel. When the tubular spout has been completely lextruded from thebody of the vessel it is only necessary to then cut the end from theextruded nose or projection and to curve the same. It is essential thatthe curving operation Vbe performed without distorting` the body ordestroying its symmetry. To this end have devised a. special press,which is the subject matter of the present invention.

It will be understood that although this press is particularly useful inconnection with the curving of the tubular integral spouts of sheetmetal c'ontainers it is not limited to this use. On the contrary, it isa machine of general application which may be used for work of widelydifferent character, and is susceptible of considerable modification fordifferent purposes, within the scope of the invention.

In the drawings:

Fig. 1 is a vertical section through the press showing a sheet metalcontainer in position to have its extruded spout curved;

Fig. 2 is a similar viewbut showing the plunger of the press at thecompletion of its working stroke; and

Fig. 3 is a t'op view of the press, the plunger being omitted.

rlhe press comprises essentially a base member 10, a stationary die 11and a plunger or movable die 12, together with additional means forsecuring the work in position to be operated on. The shaping member ordie 11 has a curved surface against y e 1,495,105?v GEORGE E. PAGE,Orr-ROCHESTER), New vonk, AssIGiiTonfTo iuoiirorin'an;nvr-iiiiiivr.y;

As previously mentioned, the invention isV particularly useful inconnection with the fabrication of sheet metal vessels having integraltubular'spouts', in accordance with the method disclosedvin my copendingapplication, but the invention is o-f general utility and not limited toany particular use and is also adapted to be embodied in variousdiiierent forms. Y l

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent is:

1. A device for curving a tubular spout formed integral with vacup=-shaped sheet metal body, comprising a base, a form for fittingagainst a supporting inner wall of the cup-shaped body during the curvinop# eration, a die into which the spout is adapted to be pressed, aplunger for bendin the spout, and means for securing the bo y to gf tsaid base With its inner wail in contact with said form and its spoutimmediately above said die. i

2. A device for curving a.

fitting against a supporting inner wallof the cup-shaped body during thecurvin 0peration, a die vinto which the spout'is a apt= ed to beVpressed, a plunger forn bending the spout, means for securing Atheb'odyto said basecwith its inner Wall in contact with i eration.
